How to Setup your Dev Environment with Pipenv and Invoke

Requirements: Node, npm, git, python3.6 or later, pip, pipenv, invoke.

If you installed Python with Homebrew, use pip3 install instead of pip install when installing the relevant requirements.

Check your environment

python --version should return 3.7 or higher,
pipenv --version should return 11.10 or higher,
invoke --version should return 0.22.1 or higher.

Setup steps

Run the following terminal commands to get started:

git clone https://github.com/mozilla/foundation.mozilla.org.git
cd foundation.mozilla.org
inv setup

If you're on windows, you need an extra step: run inv manage createsuperuser to create an admin user.

You're done 🎉

To catch up on new dependencies, migrations, etc. after initial setup, you can use the inv catch-up command.

For more information on how to run this project, check the local development with invoke and pipenv documentation.

Testing

When relevant, we encourage you to write tests. You can run the tests using the following command

inv test

In addition to the code tests there are also visual regression tests, located in the ./cypress/integration directory. You can run these tests locally by installing cypress using npm i [email protected], after which the command npm run cypress will run these tests locally. However, note that these tests are currently intended for screenshot comparisons across branches, and so will not yield any meaningful results when run for a single branch.

How to Setup your Dev Environment with Docker

Install Docker Desktop (macOS and Windows). For Linux users: install Docker CE and Docker Compose. If you don't want to create a Docker account, direct links to download can be found in this issue,
Check your install by running docker run hello-world,
If relevant: delete your node_modules directory (rm -rf node_modules). It's not necessary, but it speeds up the install.
Run invoke docker-setup (install invoke if you don't have it yet). If you're running on Windows, you need to run docker-compose --rm pipenv run python network-api/manage.py createsuperuser when the setup is finished.

This task is copying your .env to the new .docker.env that is in charge of managing your environment variables while running Docker. The installation will take a few minutes: you need to download images from the Docker Hub, install JS and Python dependencies, create fake data, migrate your database, etc.

When it's done, run docker-compose up, wait until the static files to be built, and go to 0.0.0.0:8000. You should have a local working version of the foundation site with fake data. When you want to stop, do ^C to shut down your containers.

For more information on how to run the project with Docker, check the local development with Docker documentation.

Mozilla Festival

The fake data generator can generate a site structure for the Mozilla Festival that can be served under it's own domain, or in the case of review apps on Heroku, where we're limited to a single domain, as a sub-directory of the main foundation site, at {review_app_host}/en/mozilla-festival.

In order to access the Mozilla Festival site locally on a different domain than the main Foundation site, you'll need to edit your hosts file (/etc/hosts on *nix systems, C:\Windows\System32\Drivers\etc\hosts on Windows) to allow you to access the site at mozillafestival.localhost:8000. To enable this, add the following line to your hosts file: 127.0.0.1 mozillafestival.localhost

Gotchas

As this is REST API and CMS built on top of Django, there are some "gotcha!"s to keep in mind due to the high level of magic in the Django code base (where things will happen automatically without the code explicitly telling you).

DEBUG=True

The DEBUG flag does all sorts of magical things, to the point where testing with debugging turned on effectively runs a completely different setup compared to testing with debugging turned off. When debugging is on, the following things happen:

Django bypasses the ALLOWED_HOST restrictions, which again can lead to 400 Bad Request errors in DEBUG=False setting.
Rather than HTTP error pages, Django will generate stack traces pages that expose pretty much all environment variables except any that match certain substrings such as KEY, PASS, etc. for obvious security reasons.
...there are probably more gotchas just for DEBUG so if you find any please add them to this list.
